Nice JSON Formatter and JS/CSS Highlighter

Nice JSON Formatter and JS/CSS Highlighter is a free Chrome extension that allows users to highlight and reformat JSON, JS, and CSS code directly in the browser. With its automatic code format detection, users can easily beautify and make JSON readable without the need for external tools.

The extension focuses on speed and simplicity, prioritizing performance over a wide range of options. Its core features include syntax highlighting, readable JSON formatting, clickable URLs, and the ability to auto-detect JSON on any page, regardless of the extension in the URL. Moreover, the extension has a low footprint as the source code is compiled, resulting in a lightweight extension that only weighs a few KB.

As a bonus, the extension also provides automatic JS and CSS highlighting. When viewing the source of a JS or CSS file, the code will be automatically highlighted, but there is still the option to view it in RAW if desired.

One of the key advantages of this extension is its safety. It was developed by a developer for personal use and does not collect any user data. Users can trust that their privacy is protected while using this extension.
